Cavity wall insulation for landlords for Swansea properties

Swansea sits in West Glamorgan. We work across the SA1 district, including nearby Briton Ferry, Gorseinon and Neath.

Work on Swansea rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Per-address photo records for Swansea properties make compliance files and EPC updates straightforward.

Exposure matters for every cavity wall. Parts of West Glamorgan face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On the rules side, in Swansea filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

Funding in Wales

In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.
